Defect Structure of Nonstoichiometric Perovskite [PDF]

Japanese Journal of Applied Physics, 1989
The Po2 dependance on electrical conductivity and the oxygen diffusion in non-stoichiometric BaTiO3 and (Ba, Ca) TiO3 ceramics were investigated. It is confirmed that the electrical conductivity of A-site-excess specimen at high temperature is decreasing with decrease of oxygen pressure.

d0 Perovskite-Semiconductor Electronic Structure

, 2010
We address the low-energy effective Hamiltonian of electron doped d0 perovskite semiconductors in cubic and tetragonal phases using the k*p method. The Hamiltonian depends on the spin-orbit interaction strength, on the temperature-dependent tetragonal ...

Perovskite-related ReO3-type structures [PDF]

Nature Reviews Materials, 2020
Materials with the perovskite ABX3 structure play a major role across materials chemistry and physics as a consequence of their ubiquity and wide range of useful properties. ReO3-type structures can be described as ABX3 perovskites in which the A-cation site is unoccupied, giving rise to the general composition BX3, where B is typically a cation and X ...

Competing Structural Instabilities in Cubic Perovskites [PDF]

Physical Review Letters, 1995
We study the antiferrodistortive instability and its interaction with ferroelectricity in cubic perovskite compounds. Our first-principles calculations show that coexistence of both instabilities is very common. We develop a first-principles scheme to study the thermodynamics of these compounds when both instabilities are present, and apply it to SrTiO$
